The new piezoelectric fabric hears the sound of the heart.

Piezoelectric nanotechnology is not a new thing. There is made research with fabric and clothes that can recharge mobile telephones. The idea of those systems is that the body movements can change to electricity by using piezoelectric fabric. But the same style of piezoelectric fibers can use as the fabric that can hear the heart. Or it can use as a microphone that can transform the resonance of layers to electric impulse and sound. 

The new acoustic fabric is made by using piezoelectric material. That material allows the fabric to hear the sound of the heart. And this thing makes it possible to create new intelligent clothes that are observing the condition of humans or animals. The clothes that are made by using this intelligent material can connect to the wristwatch-size computer that resends the biometric data to the mobile telephone. And the mobile telephone can communicate with any computer in the world. 

But the same system can use as the microphone. The user can put acoustic fabric against a table or to the wall. And that thing resends oscillation of the layer to the computer that can decode those signals to sound. The acoustic fabric can use in microphones that are looking like fabric boards. That thing opens new visions in the eavesdrop and recording tools. 

The same fabric can use to make new microphones that are allowing to hear things that are happening behind the wall. The idea of this kind of microphone is that the acoustic fabric is put against the wall. And then the user of that system can connect the fabric to the small computer and then to the mobile telephone. That allows sending the information about discussions to long-distance through the internet.

Use virtual "perpetual motion machines" and seawater as energy sources.

   Use virtual "perpetual motion machines"  and seawater as energy sources.  The Archimedean screw can offer almost endless energy sources.  "Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving. It is widely credited as the first attempt to describe such a device." (Wikipedia/Perpetual motion) The term "virtual perpetual motion machine" means a machine. That pulls water to the upper tank using a capillary tube. Then that water will fall through the generator or turbine wheel. The machine uses differences in pressure levels. But it looks like a "perpetual motion machine", that is impossible because of laws of thermodynamics.  The machine uses differences in pressure levels. But it looks like a " real perpetual motion machine", which is impossible because of the laws of thermodynamics.  The real perpetual motion machines don't use outside energy. And that's why they are not possible....

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger.  The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth.  It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons.  It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field.  An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate.  AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru...
